CO OLING AND -CONDENSING AP PARATUS.

SPEIFICATION forming`I part ofv Letters Patent No. 658,899, dated October 2, 1900.

Application filed. December 7, 1899. Serial No. 739,492. (No model.)

To aZ whom, it maly concert/1,:

Be it known that I, HENRY D. PowNALL, a citizen of the United States, residing at Cincinnati, in the countyof Hamilton and State of Ohio, have invented certain new and useful Improvements in Cooling and Condensing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention,--such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in Cooling and condensing mechanism.

One of the objects is to provide means whereby the impure sulfur and saline charged water of Artesian wells may be utilized for condenser and cooling purposes.

Another object is to prevent scale forming on the condenser-pipes.

Another object is to provide an improved non-corrosive heat-exchanging mechanisin for the above purpose.

Another obj ect is to provide a non-corrosive heat-exchanger whiohcan be molded or built up in molds at a single operation.

Another object is to provide vdetachable heads of non-corrosive material.

Another object is to provide improved water-tight joints between non-corrosive parts for the purpose specified. p

My invention also consists in the certain details and combination of parts, all of which will be fully desoribed in connection with the accompanying drawings, in which- Figure l is a Vertical section through my improved heat-exchanger mechanism on line y y, Fig. 2. Fig. 2 is a horizontal section on line x Fig. 1. Fig. 3 is a perspective view of one of the stud-bolts for securing the heads in place. Fig. 4 is a section on line z z, Fig. 1. Fig. 5 is aninside plan View of the righthand head, Fig. 1. Fig. 6 is an inside plan view of the left-hand head, Fig. 1. Fig. 7 is a detail sectional view of a modified joint or oouplng for the pipes. Fig. 8 is a plan view of one of the pipe coupliug-rings. Fig. 9 is a diagram of myirnproved condensing orcooling mechanism. Fig. 10 represents a modification of Fig. l. Fig. 11 is a top plan View of Fig. 10 with head removed.

Great trouble has been experienced heretofore in employing deep-Well water charged with sulfurous compounds, sulfnreted hydrogen, sult'urous oxid, salt, dac., for cooling and condensing purposes in ice-factories, distilleries, and brewerieson account of the corrosive action of the sulfurous and saline compounds upon the pipes, tanks, framework, and all metal parts coming in contact therewith, necessitating the frequent replacing of the same. 'In my improved apparatus I overcome these difficulties and yam enabled to use these Waters as they come direct from the well for all ordinary cooling and condensing purposes, as shown in the accotnpanying drawings..

A, Fig. 9, represents the condenser-coils of an ice-machine or steam-condenser.

B representsapump oironlating pure Water through pipe C over the coils A.

D represents a receptacle formed g-sme or ceinentjma.oojilinatonflthereofl so as to be unatfected by the sul'furgllwater. Located within this receptacle and with their open ends projecting through the end walls a thereof are a series of tubes E, of glass, porcelain, gutt-a-percha, or other similar noncorrosive substance. Incasing the ends of these tubes are remova'ble heads F F', provided With partitions, which serve to direct the current of water successively through the several tubes E in tandemseries.

G represents baff1e-plates,causing the water in the receptacle D, surrounding the tubes, to travel in a circuitous route from the bottom to the top thereof. This receptacle D is preferably formed at asingle operation by molding a suitable composition of Portland 01' other cement and stone, sand, or gravel over cores containing the tubes, so that when the core is removed the tubes are left firmly embedded in the cement of the end Sections of the receptacle. If preferred, however, the tubes may be subsequently inserted and made replaceable or detachable, as indicated in Fig. 7, in which l represents a metallic ring embedded in the composition of the end Sections; 2 represents stud-bolts projecting therefrom; 8 represents a gland, and 4 represents a rnbber packing-ring, which is compressed into position around the end of the tube to form a water-tight joint.

The Warm pure water after passing over the coils A is caught in the pan K and fed through the pipe H to the tubes E of the receptaele, being directed by the heads, as indicated by arrows in Figs. 1 and 2, so as to successivcly traverse the several tttbes and emerge through the pipe C, from whence it is circulated by the pump B over the coils A. The cold sulfurous water enters the receptacle D through the pipe I near the bottom and rises in a circuitous path, as indicated by arrotvs, su rrounds the tttbes E, and cools the water circnlating therein without coming in cot'ltaet therewith and escaping through pipe N. By using distilled or other pure water I wholly obviate the difficulty of forming scale upon the condenser-coils, which is one of the greatestdiflieulties experieuced in the use of condensers, and at the same titne secure the requisite quantity of condensingwater at approximately the same temperature as that of the impu re deep-well water.

In order to strengthen the heads F I",which are preferably molded from a composition in the same manner that the receptacle is formed, I emhed a perforated metal plate L in the material of the head. 5 represen ts eyebolts to assist in removing and replacing the head. The heads are secured in place by means of stud-bolts 6, which are screwed into cast-metal bosses 7, anchored in the body of the receptacle.

In the tnoditication shown in Figs. 10 and 11 the sulfnreted water enters through pipe I' and escapes through pipe N', while the pure water enters the chatnber 8 beneath the head 9 and passes from thence through the several tubes simultaneously ot' in tnttltiple series to the chamber 10, from whence it emerges cooled and passes to the condensercoils.

d d' represent removable sections to permit access to theinterior of the receptacle D.

g represents passages for the water, cored in the body and heads of the receptacle.

I'Ia\"ing described my invention, what I claim is-- 1. In a cooling and condensing apparatus, a coil of pipes in which the medium to be cooled or condensed is circulated, a non-corrosive receptacle through which the impure cooling-water is circulated; a series of noncorrosive tubes spanning `said receptacle; a body of pure water; and means for circulating it first through the tubes of the recepta- Ole, where it is cooled, and then in contact with the condenser-coils, substantially as specified.

2. In a cooling and condensing apparatus a coil of pipes in which the medium to be condensed is cireulated; a non-corrosive receptacle through which the impure Coolingwater is circulated, a series of non-corrosive tubes spanning said reeeptacle; removable heads inclosing the ends of said tubes; a body of pure' water and means fot' circttlating it first through the tnbes of the receptacle, where it is ('.ooled and then in contact with the condenser-eoils,substant.iallyasspecitied.

3. As a new article of manufacture a cooling and condensing apparatus consisting of a receptacle molded from cementI or other Vitt'eous composition; tubes of vitreous ma' terial spanning the same; heafls with recesses forming connecting-passages between the tubes, metalstuds bedded in the composition fot' securing and holding the heads in place; and outside pipe connections directing the different mediums respectively to the inside and outside of said tubes, substantially as specified.

4. In a cooling and condensing apparatus, a receptacle molded in a single piece from cement or other similar vitreous material; a series of tubes of vitreous material spanning the same; removable heads incztsing the ends ofsaid receptacle and provided with recesses forming conneeting-passages between the pipes; means substantially as described for detachably securing the heads in place; and outside pipe connections direct-ing the different mediums' respectively to the inside and outside of said tubes, substanttally as specified.

In testimony whereof I have aflixed my signature in presence of two witnesses.

HENRY D. POWNALL.
